Abstract
Abstract: Now everywhere in the world sensors are used to solve daily human problem. In the medical field sensors are used to diagnose various diseases. In this article for detection of tuberculosis, micro cantilever biosensor has been design and simulate. Rectangular shape cantilever biosensors with silicon, poly-silicon and aluminium material were designed and analysed the displacement. The displacements of this biosensor are compared with the other available models. The MEMS based micro cantilever biosensor were design in COMSOL Multiphysics. 10N to 100N load force are applied on the surface of cantilever for deliberate the interaction of antigen antibody. Stress generated on the surface of cantilever when antigen antibody binds together and it get deflects. This deflection is measured for 10N to 100N load force which is compare with other modules. The displacement generated by cantilever was 1.71 x 1028 µm for 100N force which is higher than all the other models, thus the proposed cantilever model is the best model for detection of tuberculosis
